• When these TSQL statements are called more than twice to split data from TempScan to 3 tables, how can I prevent duplicated data to be inserted into Vulnerabilities table. • With TSQL#2, a duplicated data won’t be inserted into ComputerInfo, however, in case someone changes some of the computer’s IP, or OS, or anything from TempScan table, and run TSQL#2, how can I delete old rows and insert new rows, or update rows that have data changed.
